Desktop Virtualization (VDI)
A. VDI Service Overview
Desktop Virtualization (VDI) is a remote desktop service for running applications that require high-performance graphics processing in a MS Windows 10 environment. VDI mounts the Nurion file system (user home and scratch directories), allowing for pre- and post-processing of engineering analyses directly on the desktop (VM) without the need for file transfers. Solving tasks are not supported on the desktop (VM). Instead, users should perform the analysis on the Nurion system by accessing it via a terminal program (such as Putty) within the desktop (VM).
The desktop (VM) pool is divided into Normal Nodes and Large Nodes, as detailed below, allowing users to select the appropriate desktop (VM) pool. To support multiple users with limited desktop (VM) resources, connections will be terminated, and the VM will automatically shut down after 2 hours of idle time.
Normal Node (8 total*): 4-core CPU, 32GB memory, 8GB GPU memory allocated. * The number of VMs may be adjusted
Currently, the following software is supported for pre- and post-processing of engineering analyses, and additional applications will be supported based on user demand.
Ansys (Workbench, SpaceClaim, CFD-Post, etc.) v2020 R2, v2023 R2
Abaqus (CAE, Viewer) v2020, v2023
Paraview v5.11.1, VAPOR v3.9.0
Salome-Meca v2023
B. How to Use VDI
1. Accessing MyKSC
Access MyKSC (KISTI Supercomputer Web Service Portal, https://my.ksc.re.kr) using a web browser.
Enter your ID, password, and OTP number for supercomputer user authentication, then select the Nurion system to log in.
Once user authentication is successful, you will be directed to the MyKSC dashboard.
2. Accessing the Desktop Virtualization (VDI) Server
Click the "Add App (+)" button on the MyKSC dashboard, select VDI (Windows 10), and the VMware Horizon page will launch in a separate window.
The VDI service can be accessed via the 'VMware Horizon Client Program' or 'Web browser.‘
* For stability, it is recommended to use the Client Program rather than the Web browser.
1) VMware Horizon Client Program
First-time users should click 'Click here to download VMware Horizon Client' to install the program, then click 'Start the Basic Client.'
In Horizon Client, click 'Add Server,' enter 'https://uag-vdi.ksc.re.kr' as the connection server name, and connect.
The previous connection server URL used by existing VDI users, https://nurion-vdi.ksc.re.kr, is no longer available.
2) Web browser
Click 'VMware Horizon HTML Access.'
3. Logging into the User Desktop
In the Horizon web or program interface, select the Large Node or Normal Node desktop pool to connect to your VM-based user desktop. If all available VMs are in use, a VM may not be allocated.
Normal Node (8 total*): 4-core CPU, 32GB memory, 8GB GPU memory allocated. The number of VMs may be adjusted
Once a desktop (VM) is allocated, you will be connected to a Windows 10 OS, which takes approximately 30 seconds.
You can view the installed software list from the desktop or start menu.
Ansys (Workbench, SpaceClaim, CFD-Post, etc.) v2020 R2, v2023 R2.

During the login process on the user desktop, the user directories of the Nurion system’s home01 and scratch are automatically mounted. If the mount fails or an error occurs, run the 'NFS' icon on the desktop.
For security reasons, access to the C:\ drive, control panel, etc., is restricted, and any files created or saved by the user will be reset upon VM shutdown. Therefore, files that need to be retained should be saved in the user home and scratch directories of the Nurion system.
After 2 hours of idle time, the connection will be terminated, and the VM will automatically shut down.
When accessing the desktop via a web browser, you can upload files from your PC by selecting 'Open File Transfer Panel' from the left menu panel.
